Nobody but doctors or nurses and those by Dr.Hu to enter the patient’s room.

A. invited; is allowed

B. are invited; are allowed

C. being invited; allowed

D. invited; are allowed

答案：

(答案→)A. invited; is allowed

B. are invited; are allowed

C. being invited; allowed

D. invited; are allowed

解析：句意：除了医生护士和胡大夫邀请的那些人再也没有人允许进入病人的房间。第一空根据by Dr.Hu可知those与invite之间是被动关系，故用过去分词；第二空是主谓一致，有介词连接的两部分做主语时，真正的主语是介词前的代词，所以整个句子的主语是nobody，不定代词作主语谓语动词用单数，
